Create a dramatic, natural look in your tank with this Dark Aquarium Substrate. Suitable for freshwater, saltwater, and terrarium setups, this fine sand provides a stunning contrast that makes plant greens and fish colors pop.
Key Features
Versatile Foundation: A neutral substrate suitable for freshwater and marine aquariums as well as terrariums.
Root Support: The fine 0.2–0.6 mm grain size allows plant roots to anchor easily and spread effectively.
Easy Maintenance: The high density and fine granulation prevent mulm and waste from sinking deep into the substrate, making surface vacuuming much easier.
Bottom-Dweller Safe: The smooth, fine grains are gentle on the sensitive barbels of bottom-dwelling species (like Corydoras and Loaches), preventing injury.
Stress Reduction: The dark, non-reflective surface mimics deep-water environments, helping shy or easily startled fish feel secure and display their full natural coloration.
100% Safe: Does not release harmful pollutants into the water.
Build a thriving planted aquarium from the bottom up with Dennerle Plants Substrate. This is a classic long-term nutrient concentrate designed to be used as the bottom layer of your tank.
How it Works
Dennerle Substrate acts as a "nutrient battery" for your plant roots. It contains natural clay minerals and peat that regulate the nutrient balance—releasing nutrients when needed and absorbing them when there is a surplus.
Key Benefits
Nutrient Depot: Provides a balanced supply of essential nutrients for healthy, vital plants.
Strong Roots: Encourages deep rooting and robust growth.
Intelligent Regulation: Buffers nutrients to prevent spikes and deficiencies.
Natural Ingredients: Safe for fish, shrimp, and snails.
Usage Instructions (Important)
Layering: Spread a layer of Dennerle Substrate (approx. 1 cm thick) on the bottom of the empty aquarium.
Capping: Cover completely with a top layer of aquarium gravel or soil (approx. 4-5 cm thick).
Note: Do not mix the layers. The gravel cap prevents nutrients from releasing too quickly into the water column.
Calculation Guide: How much do I need?
Formula: (Length cm x Width cm x Layer Height cm) / 1000 = Liters needed.
Example: For a 60x30cm tank with a 1cm layer:
60 x 30 x 1 / 1000 = 1.8 Liters (You would need a 2L bag).
Pro Tip: If moving plants later, pull them out slowly and cut roots just above the substrate to avoid stirring up the bottom layer and clouding the water.
Keep your aquarium plants lush and healthy with the Dennerle Bio CO2 Starter Refill. This package is the official refill set for the Dennerle Bio CO2 Starter Kit, providing an additional 60 days of biological CO2 production.
Why Choose This Refill?

Complete Set: Contains everything you need to restart the fermentation process.
Consistent Growth: Ensures there is no gap in nutrient supply for your aquatic plants.
Package Contains
1x CO2 Powder Mix
5x CO2 Activator packets
Maintenance Tip
For optimal CO2 levels, refill the CO2 Activator every 14 days or whenever production drops below 5 bubbles per minute.
Please Note: This is a refill pack only. The plastic bottle, hose, and diffuser are NOT included (sold separately in the Starter Kit).
Build a professional-grade foundation for your aquascape with Yokuchi Ganban Power Base. This is an advanced "power base" designed to be placed under your main substrate or soil to supercharge your aquarium ecosystem.
How it Works
Ganban Power Base is a carefully selected mixture of natural volcanic and organic materials. Its highly porous structure creates the perfect habitat for beneficial bacteria, which filter the water and break down metabolic waste from fish and plants.
Key Benefits
Biological Filtration Engine: High pore saturation supports massive colonies of microorganisms that clean your water from the bottom up.
Nutrient Rich: Slowly releases essential nutrients to plant roots, promoting robust growth and stability.
Long-Term Health: Helps prevent anaerobic pockets and maintains a healthy biological balance in the substrate.
Usage Instructions
Spread a layer of Ganban Power Base on the very bottom of the empty aquarium, then cover with your preferred aquarium soil (e.g., Yokuchi Jiban or Dennerle Soil).

Transform your aquarium with JBL Manado Natural Substrate. This porous, natural substrate is designed to support lush plant growth while maintaining a healthy ecosystem for your fish.
Key Features
Nutrient Battery: The highly porous structure absorbs excess nutrients from the water column and releases them directly to plant roots when needed, preventing algae growth.
Enhanced Filtration: Its massive surface area encourages the colonization of beneficial bacteria, effectively turning your entire substrate bed into a biological filter for crystal-clear water.
Root Development: The lightweight, rounded granules promote strong root growth and are gentle on the sensitive barbels of bottom-dwelling fish like Corydoras.
Natural Look: Provides a warm, natural appearance that enhances the colors of your fish and plants.
Why Choose Manado?
Unlike inert gravels, Manado actively improves water quality by storing nutrients and supporting beneficial bacteria. It creates the ideal environment for vigorous plant growth and a stable, healthy aquarium.

Green or cloudy water caused by algae, excess feeding, and fish waste can spoil the appearance of an aquarium and may disrupt pH and oxygen levels.
Algae Gone is a plant-safe, single-dose treatment that clears green or cloudy water by binding tiny particles together (flocculation) so they can be easily removed by your filter.
Key Benefits
Crystal Clear Water: Clumps suspended algae and waste particles together so your filter can catch them.
Phosphate Control: Helps reduce algae-causing phosphates, preventing future outbreaks at the source.
Safe Formula: Completely safe for aquatic plants and fish.
Fast Acting: Single-dose treatment designed to tackle bloom issues quickly.
When to Use
Use immediately when aquarium water becomes green (suspended algae) or cloudy (bacterial bloom or waste).
Dosage Instructions

Substrate Reboot: Ideal for older aquariums where the soil nutrients have been depleted over time.
Nutrient Declaration (NPK + Micro)
Nitrogen (N): 21%
Phosphorus (P): 7%
Potassium (K): 11%
Plus: Magnesium (2%), Copper, Iron (0.1%), Manganese.
How to Use
Placement: Use tweezers to insert capsules deep into the substrate at the base of the plant.
